IMPROVEMENT IN STOVE-OVEN SHELVES.

Specification forming part of Letters Patent No. 205,754, dated July 9,1878; application filed May 13, 1878.

To all whom 'it may concern:

Be it known that we, EZEKIEL O. LITTLE and DAVID H. NATION, residents ofSt. Louis, Missouri, have made a new and useful Improvement inStove-Oven Shelves, of which the following is a full, clear, and exactdescription, reference being had to the annexed drawin g, making part ofthis specification, in which- Figure 1 is ahorizontal section takenthrough a stove embodying the improvement, showing the shelf let down,and showing only the parts immediately connected with theimprovementFig. 2, a similar section, the parts being as when the oven-door isclosed and the shelf turned up; Fig. 3, aview, in perspective, frombeneath of that portion of the shelf shown in Figs. 1 and 2; Fig. 4, anelevation, looking in the direction of the arrow as of Fig. 1, of thatportion of the oven-door shown in Figs. 1 and 2, and showing also thatpart of the stove to which the door is hinged; and Fig. 5, an endelevation of that portion of the oven-door shown in Figs. 1, 2, and 4,looking in the direction of the arrow 3 of Fig. 1; Fig. 6, a View, inperspective, of the improvement and of the parts immediately therewithconnected; and Fig. 7, a detail, being a view, in perspective, from theinner side thereof (and looking from the position of the door-hinge) ofa portion of the oven-shelf and of the oven-door, the parts being as inFig. 6.

The same letters of reference denote the same parts.

The present is an improvement in that class of oven-shelves that areoperated by the movement of the oven-door, and that, when the oven-dooris shut, are inclosed within the oven, but when the oven-dooris opened,are let down outward therefrom, forming a hearth just without the oven,and preferably even with the oven'bottom.

In the present improvement the shelf is operated by a projection on theoven-door coming directly into engagement with a projection upon theshelf, and the improvement has especial relation to the peculiar shape,arran geinent, and operation of these projections.

Referrin g to the drawing, A represents the stove-oven; I), theoven-door, andC the oven.-

shelf. The latter is supported by arms 0, that are journaled in suitablebearings c, and by means of which the shelf can be turned up within theoven or let down on the outside thereof. The shelf, atthe end toward thedoor and near the inner edge of the shelf, is provided with aprojection, D, that stands up from the shelf, and inclining slightlytoward the door, as indicated more distinctly in Fig. 2. At its upperend the projection has an extension, d, that projects horizontallytoward the inner end of the door. The projection is further, and on theside toward the door, provided with a rib, d, that extends from the extension d downward, curving around, as shown in Figs. 2 and 3.

The door B is furnished with a projection, E, that projects from theinner face of the door far enough and so as to come past, opposite, andagainst the outer side of the extension (I when the door is in theposition of Fig. 1. The projection E, at its outer end and on the sidetoward the extension (I, is beveled, as shown at 0, Figs. 1, 2, 4, and5. This bevel is pref erably hollowed out slightly, as shown moredistinctly at c, Fig. 1. The nose of the projection E is also rounded ina vertical direction, as shown at 0 Figs. 4 and 5; and the projection isalso preferably extended at 6 Figs. 1, 2, and 4, in the direction of theouter end of the oven-door.

To lift the shelf, the door is moved into the position of Fig. 1. Thebevel e of the projec- -tion E comes against the outer side of theextension d, causing the shelf to be lifted slightly. As the doorcontinues to close, the nose of the projection passes down against therib d causing the shelf tobe lifted higher and higher, until finally theparts are brought into the position shown in Fig. 2-that is, the nose ofthe projection E, as the two parts D and E move upon each other, firstrides diagonally downward and across the rib (1 until it is close to themain part of the projection at 61 and then rides diagonally downward andback toward the outer lower end of the rib d, and when the door is shut,the extension 0 is brought against the lower end of the rib al as inFig. 2, and serving to hold up the shell sufficiently to keep the latterfrom coming in con fact with the inner face of the door. The let- Ipresent improvement is that the movement of the door in closing isgradually imparted to the shelf. However suddenly the door is swung to,the shelf is never struck violently; but its lifting is initiated easilyand gently and the entire movement effected quietly. This is owingmainly, to the projection on the door encountering first the extension(I of the part D, and then to its winding down and around the rib d, inthe manner described.

"We are aware that stove-oven shelves have been lifted by means of theoven-door, and that projections have been used upon the door and alsoupon the shelf; and also that the projection on the door has beenfurnished with a roller. The latter is valuable in reducing thefriction; but it is liable to be broken in suddenly closing the door,and it increases the cost of the construction. By means of the peculiarshape of the parts E and D we are enabled to dispense with a roller, andyet be able to operate the shelf as easily as when a roller is used.

Ve claim 1. The combination of the door 13 and the shelf 0, the formerhaving the projection E, having the bevel 0, and the latter having theprojection I), provided with the extension (I and rib d substantially asdescribed.

2. The door B, having the projection E, provided with the extension 0and having the bevel e, in combination with the shelf 0, havin g theprojection D, provided with the extension (1 and the rib d, as and forthe purpose described.
